A buddy of mine bought a few used Cannon Mag 20 down riggers, and included in the package deal was a New in the box LC 787C2-I Hummingbird sonar unit.
Im not sure how old this sonar is although I don't think its still being sold anymore.

Its 4,000 watts (500 watts rms) and as mentioned never been taken out of the box and included is the transducer and all the other stuff.The original price on the box was from west marine was $800.00.

Another friend of ours is interested in buying it and asked me if it was a decent sonar.Im not much help as Im happy with my Simrad/NorthStar sonar.

Can anyone tell me whether or not its a good sonar. his use would be mostly for lake trout and atlantic salmon trolling in New England lakes.

Any info good or bad would be appreciated. Thanks for any help
